Lung adenocarcinoma (LUAD), the main subtype of non-small cell lung cancer, is known to be regulated by various microRNAs (miRs/miRNAs); however, the role of miR-198-5p in LUAD has not been clarified.
Results showed that miR-198-5p overexpression could inhibit the migration, invasion and epithelial-to-mesenchymal transition (EMT) of NSCLC cells; reversely, suppression of miR-198-5p enhanced cell migration, invasion and EMT.
Here, reduced levels of FSTL1 were detected in various tumors compared with normal tissues and were associated with poor clinical outcome in patients with non-small cell lung cancer, particularly those with lung adenocarcinoma.
In this study, to investigate the clinical significance of miR-198 in NSCLC in relation to the response to radiotherapy, we determined the expression patterns of miR-198 between responders and nonresponders after 2 months of radiotherapy and found that decreased expressions of miR-198 were associated with radiotherapy resistance.
In this study, we detected the expression of FSTL1 in a panel of NSCLC cell lines and lung normal epithelial cell line by qRT-PCR and western blot analysis and found that FSTL1 was downregulated in NSCLC cells compared with normal control.
We found a correlation between expression of TSC-36 and cell growth: TSC-36 mRNA was not detected in cells derived from small cell lung cancer (SCLC) cells, a highly aggressive neoplasm, but was detected in some non-small cell lung cancer (NSCLC) cells, a moderately aggressive neoplasm.
